Best tubes for ARC LS16 preamp

thanks for the suggestions ,i just ordered a siemens nos ,the cca was a bit too pricey so i went w/the 70's stock,platinium,acording to joe's tube lore,it'll still be an improvement,thanks

I have an LS-16 with the original factory tubes. Where would you suggest to buy new tubes?

Joeavid...please let us know what differences you notice when you get the new tubes going.

Does anyone have feedback on the AR upgrade ($1095) for the LS-16?

Thanks

I´m also curious to know how the original LS16 stack up to the MKII status.

Thanks,

Just got siemens 6922 e88cc today,gold pins west germany(1960's)...from tube world,a bit pricey @$105 each.Asked my dealer re:upgrade to mk11 status but he hasn't heard it yet,so i'll keep you guys updated...

Thanks for the info Albert. I have a pair of Siemens 6922 E88CC and 6922 CCas at home as well as a pair of Mullards on the way. I can't wait to try them out in my DAC.
